Embodiment approach

[0110] As an optional embodiment, the method further includes:

[0111] receiving, by the terminal, a second physical layer command sent by the network side device, where the second physical layer command is used to cancel the uplink transmission control of the target logical channel by the first physical layer command;

[0112] The terminal cancels the uplink transmission control of the target logical channel according to the second physical layer command.

[0113] The above-mentioned second physical layer command may be that the PDCCH contains DCI, and of course, may also be other physical layer commands, which is not limited.

[0114] The above cancellation of the uplink transmission control of the target logical channel by the first physical layer command may be to restore the uplink transmission control performed in step 202 .

[0115] For example: the above first physical layer command is to prohibit the target logical channel from performing uplink transmission, so tha...

Embodiment 1

[0158] In this embodiment, the dynamic scheduling command indicates that a specific logical channel cannot use this resource, wherein the DCI indication content may be:

[0159] 1. The DCI contains a logical channel indication, and the specific indication mode can be LCID, or the number of a configured logical channel that can perform special operations, or a bitmap indicates all configured logical channels that can perform special operations. or

[0160] 2. The DCI only contains 1-bit disable indication: the indication is used to determine whether the configured logical channel is prohibited from using the current dynamic scheduling resources. The logical channel that can be disabled is pre-configured by RRC signaling and / or MAC layer signaling. or

[0161] 3. The DCI contains the logical channel indication and the indication of whether it is disabled.

[0162] In this embodiment, the base station side includes the following steps:

[0163] Step 1: The base station uses RR...

Embodiment 2

[0169] In this embodiment, the dynamic scheduling command instructs a specific logical channel to use the resource this time with the lowest logical channel priority, wherein the content of the DCI indication may be:

[0170] 1. The DCI contains a logical channel indication, and the specific indication mode can be LCID, or the number of a configured logical channel that can perform special operations, or a bitmap indicates all configured logical channels that can perform special operations. or

[0171] 2. The DCI only contains a 1-bit enable indication: this indication is used to determine whether to lower the priority of the configured logical channel in the current dynamic scheduling resource. The configured logical channel is pre-configured by RRC signaling and / or MAC layer signaling . or

[0172] 3. DCI contains logical channel indication and enable indication. or

[0173] 4. The DCI contains the logical channel indication and the reduced PBR indication. or

Abstract

The present invention provides a method for controlling uplink transmission, a terminal and a network side device. The method includes: the terminal receives a first physical layer command sent by the network side device, wherein the first physical layer command is used to prohibit the target logical channel from performing uplink The transmission either reduces the transmission priority of the target logical channel or limits the transmission rate of the target logical channel; the terminal executes uplink transmission control corresponding to the first physical layer command for the target logical channel. Embodiments of the present invention can reduce waste of resources.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an uplink transmission control method, a terminal and a network side device. Background technique [0002] In some communication systems, the design of the logical channel priority only considers the traffic required by the burst data within the Packet Delay Budget (PDB), so the transmission rate of the logical channel in the actual transmission process may be much greater than the guaranteed rate. Flow rate (Guaranteed Flow Bit Rate, GFBR), thereby occupying resources of other logical channels, resulting in waste of resources. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide an uplink transmission control method, a terminal, and a network-side device, so as to solve the problem of resource waste. [0004] An embodiment of the present invention provides an uplink transmission control method, including: [0005] The terminal ...
